The PinusResina initiative aims to identify/establish new value chains for the competitive and safe transformation and recovery of pine resin in high value-added products, with the mission of increasing the competitiveness and sustainability of Pinus pinaster and Pinus pinea forest in Portugal, in particular by enhancing resin constituents for new fine chemistry markets - resin chemical industry as the main economic factor in pine ecosystems; toxicity assessment of derived products; analyze the variability of resin composition, biotransformation and the exploitable capacity of waste resulting from its exploitation; and evaluate the sustainability of new value chains.
SiResin - Resin Information System
The Decree-Law nº 181/2015, defines the legal regime for the resin activity and circulation of pine resin in Continental Portugal. The regime requires prior notification to the Portuguese Institute for Nature Conservation and Forestry (ICNF) of resin tapping, resin import and export, resin transportation and storage and resin used by 1st transformation industry. The communication is made online through the Resin Information System (SiResin):
Supercritical CO2 extraction technique
After harvesting, the resin takes the form of a homogeneous mixture. Its distillation makes it possible to obtain two products: rosin and turpentine oil. The objective of extraction is to isolate and sample these compounds accurately. In other words, it is a question of having the finest possible selectivity. The second objective is not to alter the molecules and thus take full advantage of its qualities.
